Title: Ionic additives for extreme low dielectric constant chemical formulations
Inventor: MANY ROBERT P
IPC: C01B33/16
Filed: 2001-04-04
Granted: 2006-01-21
Abstract: A process for depositing porous silicon oxide-based films using a sol-gel approach utilizing a precursor solution formulation which includes a purified nonionic surfactant and an additive among other components, where the additive is either an ionic additive or an amine additive which forms an ionic ammonium type salt in the acidic precursor solution. Using this precursor solution formulation enables formation of a film having a dielectric constant less than 2.5, appropriate mechanical properties, and minimal levels of alkali metal impurities. In one embodiment, this is achieved by purifying the surfactant and adding ionic or amine additives such as tetraalkylammonium salts and amines to the stock precursor solution. In some embodiments, the ionic additive is a compound chosen from a group of cationic additives of the general composition [NR(CH3)3]+A-, where R is a hydrophobic ligand of chain length 1 to 24, including tetramethylammonium and cetyltrimethylammonium, and A- is an anion, which may be chosen from the group consisting essentially of formate, nitrate, oxalate, acetate, phosphate, carbonate, and hydroxide and combinations thereof. Tetramethylammonium salts, or more generally tetraalkylammonium salts, or tetraorganoammonium salts or organoamines in acidic media are added to surfactant templated porous oxide precursor formulations to increase the ionic content, replacing alkali ion impurities (sodium and potassium) removed during surfactant purification, but which are found to exhibit beneficial effects in promoting the formulation of the resulting dielectric.

Title: Radio communication system and method of operationg the same
Inventor: BAKER MATTHEW PETER JOHN
IPC: H04L12/28
Filed: 1999-12-30
Granted: 2002-12-01
Abstract: A radio communication system has means for ensuring that power control of a communication channel has been established before the transmission or data. This is done. by delaying initial transmission of a data channel (either at the start of a transmission or after a pause) until after the initial transmission of control channels, in one embodiment the transmission of a data channel can be delayed until adequate power control has been established. These techniques overcome the problem that data transmissions at the start of a data channel are likely to be corrupted if their power level is too low, or to generate extra interference if their power level is too high. The radio communication system also has means for improving power control of a communication channel for the transmission of data after an interruption in the transmission. This is done by applying power control in steps of variable size at the start of a transmission, using a large step size initially which is reduced as the power approaches a target value. In one embodiment the step size is reduced when the sign of a power control command reverses, while in another embodiment the step size is reduced after a predetermined time. These techniques reduce the time taken for power control to be established, thereby addressing the problem that data transmissions at the start of a data channel are likely to be corrupted if the power level is too low, or to generate extra interference if the power level is too high.

Granted: 2004-10-11
Abstract: An e-mail processing system, processing method and processing device includes a provider connected to personal computers (PCs) and a portable telephone or a PHS or a PDA via Internet. In the provider, the content of a received e-mail is compressed by a keyword analysis to obtain a short text of the e-mail, and the short text is sent from the provider to the e-mail receiver via the Internet. The e-mail receiver receives and displays the short text to immediately understand the content of the received e-mail. The whole short text can be displayed on a small screen of the portable telephone (PHS) or the PDA without scrolling the displayed e-mail. The provider can rearrange the received e-mail in order of receiver's priority and send the rearranged e-mail to the e-mail receiver via the Internet. The receiver can receive and read in his optimum order with ease of use, and the e-mail requiring an urgent action can be preferentially displayed. The provider can convert the e-mail text document into voiced e-mail and sends the voiced e-mail to the receiver via the public telephone network. The e-mail receiver can listen to the voiced e-mail using the telephone such as the portable telephone (PHS) without using the PC or the PDA.

Title: Gain linearizer for variable gain amplifiers
Inventor: WALKER BRETT C
IPC: H03G7/08
Filed: 2001-10-09
Granted: 2005-07-01
Abstract: Techniques to linearly (in dB) adjust the gains of variable gain elements (i.e., variable gain amplifiers or VGAs) in a receiver or transmitter. An input control signal is provided to a conditioning circuit that conditions the control signal to achieve various signal characteristics. The input control signal is limited to within a particular range of values, temperature compensated, scaled (or normalized) to the supply voltages, shifted with an offset, or manipulated in other fashions. The conditioned signal is then provided to an input stage of a linearizer that generates a set of exponentially related signals. This is achieved using, for example, a differential amplifier in which the conditioned control signal is applied to the inputs of the differential amplifier and the collector currents from the differential amplifier comprises the exponentially related signals. An output stage within the linearizer receives the exponentially related signals and, in response, generates a gain control signal. By approximately matching the output stage to a gain stage of the variable gain element and by using the gain control signal generated by output stage, the gain transfer function of the VGA approximates that of the exponentially related signals.

Granted: 2004-01-11
Abstract: A driving circuit and a method for a display device and a display device with the driving circuit and driving method. A discharge unit is added in a driving unit for a electroluminescent unit. The discharge unit is turned on by a next scan line. When the driving circuit sequentially turns on all of the scan lines in the display device, the discharge unit for a corresponding driving unit will be turned on by the next scan line when the next scan line is turned on. The turned-on discharge unit will discharge the voltage level applied to the electroluminescent unit to avoid materials of the electroluminescent unit being damaged by the electrical charges accumulated by a long-term voltage applied to the electroluminescent unit. If the materials of the electroluminescent unit is damaged, it causes resistance of the electroluminescent unit increasing, to cause the driving voltage therefore increasing and shorten the life time of the device.
